PICTURE-PRO J ECTIN G APPARATUS.
Application led February 21, 1923. Serial No. 620,363.
This invention relates to apparatus comprising a cabinet, a picture-projector therein and a screen movably connected with the cabinet, and an object of the invention, -in general, is to improve the construction dlsclosed in United States Letters Patent No. 1,385,955, granted to me July 26, 1921.
Another object of the invention is to mount the screen upon a closure for the cabinet, so that the screen can be closed into the cabinet by shutting of the closure. This distinguishes from the above mentioned patent in that the screen support and the closure were separate members in said patent and did not operate together. Thus I have simplified the construction and operation of the apparatus.
Another improvement is the supporting means for the closure on which the screen is mounted. v
The accompanying drawings illustrate the invention:
' Figure 1 is a side elevation of an apparatus embodying the invention, the parts being shown in position for projecting pictures upon the screen.
Fig. 2 is a front elevation of the ap aratus, the lid being down and the screen ing closed into the cabinet.
Fig. 3 is an enlarged fragmental vertical section of the apparatus, the parts being shown in solid lines in the positions they occupy in Figure 2, and the screen and its s lipporting means being shown in broken lines in the positions they 'occupy when the support is elevated and the screen is collapsed.
Fig. 4 isan enlarged sectional detail of the support and screen in the same position as in Figure 3. Fig. 5 is an enlarged sectional detail of the latch for the bracket that holds the support in open position.
Figf is an enlarged elevation of the apparatus from the right of Figure 1, the li eing omitted.
Fig. 7 is a sectional elevation similar .to Figure 3, excepting that the screen and its support are in the same positions as in Figures 1 and 6.
Fig. 8 is an inverted tion of Figure 7.
There is provided a cabinet 11 of any suitable construction and said cabinet is rovided with a hin ed lid 12 adapted, w en closed, to cover t e projector 13, which is mounted on the cabinet. The lid, however, is not essential and maybe omitted. The
plan view of a porcabinet 11 is provided in its front with a recess 14 and, if it is desired to separate said recess from other portions of the interior. of the cabinet, this maj7 be done by a partition, indicated at 15. Such partition, however, is not necessary, but it adds to .the appearance of the apparatus when the recess closure, indicated at 16, is in position to disclose the recess.
The closure 16 is movably mounted, being hinged at its upper edge at 17 to the cabinet 11, and constitutes a vertically swinging door for the recess. Not only does the door 16 serve to close the recess, but it also functions, When elevated, as in Figure 1, as a support for a screen 18. The screen 18 is preferably collapsibly mounted on the door and, in this instance, is hinged at 19 to that face of the door that .is undermost when the door is raised and that is turned inwardly when the door is closed. The hinges 19 comprise brackets 20, secured to the inner face of the door 16, and L-shaped arms 21 Secured to the side edges of the screen. The arms 21 enable the screen 18 to be swung into position abutting the outer end of the door 16 as in Figure 1 so as to project the screen into position above the level of said 'door and in axial `alinement with the projector when the door is open or horizonta To yieldingly hold the screen 18 in its open or elevated position coil springs 22 are secured at one end to the edge of the screen 18 that is nearest the hinge 19, and the other ends ofthe springs 22 are connected to the under face of the door 16 so that when the screen is in open position, as in Figure 1, the
springs will be under tension and therefore tend to hold the screen open against the edge of the door, which edge thus constitutes an abutment to limitmovement of the vscreen towards the projector. When'the screen 18 is swung into closed position, as in Figure 4,- the springs 11e between the screen and the vunder face of the door.
Means are provided to hold the screen inf its collapsed position and, though any suitable means may be employed for this purpose,`I have shown in the drawings an Lf shaped latch 23 pivoted at 24' to the under ressure of the spring 26 to retract the shouler from engagement with the screen, thus ermittin the screen to swin downward y from t e door. Then, to p ace the screen in position for use,'the operator will swing the same outwardly and upwardly against the tension of the springs 22.
Means are provided to support thedoor 16 in its elevated position and, though such means may be variously constructed, I have shown in the drawings the construction 'at present employed. This construction is as follows:
Arms 27, that converge downwardly and inwardly when the door is elevated, are pivotally connected or hinged at 28 to the inner face of the door 16. The hinge, in this instance, comprises a rod 29 supported by ears 430 aliixed to the inner face of the door. The arms 27,. if desired, ma be connected at their divergent ends by a race 31. Through the conver entends of the arm 27 extends a pin 32 wich operates ina slot that comprises two ways or limbs 33, 34, there being a shoulder 35, at the intersection of the limbs `33, 34, to constitute an abutment, against which the pin 32 seats when the door is in open osition,-as in Figure 7. To close f the door, t e operator will .elevate the rear ends of thearms 27, thus moving the pin 2 away from the abutment 35 and into the llmb 33 of the slot. It will be noted that the shorter limb 34 of the slot is nearer the swinging member or closure 16, thus preventing shutting of the closure unless the operator (graspsone of the arms 27 with one hand an forces it inwardl after having raised the closure with the ot er hand. This construction avoids accidental closin' of the member 16 in case said member is lnadvertently raised orknocked upwardly. 'Ihe operator then allows the door to close and this 'causes the in 32 to travel downwardly in the slot. o open the door and latch the same in its open osition, the operator will raise the .door as' igh as possible and, when the gin 32 travels from the upper end of the s ot the arms to dro to seat the in against the shoulder. The s ot 33, 34 may be constructed in any suitable manner and, in this instance, is formed in partby a slotted casting 36 and in part by a metal strip 37 and the partition 1 5, the strip 37 being spaced from the partition and secured at one end to the casting `36 and at its opposite end to the licor 38 of the recess 14;.
When it is desired to roject pictures onto the screen, the door will) be opened and the screen elevated in' a manner hereinbefore described so as to position the screen in front of the projector 13, as in Figure 1.
If desired, the door 16 may be releasably held in closed position by one or more of the well known ball catches'indicated at 39.
imb 33 into the limb 3%ravit'y causes These ball catches are well known in the cabinet makers art and it is therefore 11n-- necessary to illustrate and describe them in detail herein. y
